Hello
If you use the "Insert PDF page" feature, a document with the same name will be created. This is a protection mechanism that cannot be disabled because different PDFs have different sizes, properties, etc. Inserting or deleting PDFs may cause the document to be lost, and the operation of deleting PDF pages cannot be undone, so to avoid such a loss, Marginnote will automatically generate a file with the same name as a backup.
You can delete unwanted documents after checking, or temporarily disable the function of inserting PDF pages.
Kind Regards,
MarginNote-Bubble
